What do you do if your Dragon Age character has multiple endings?

Ok I wanted the Perfectionist achievement (Expierence all possible endings) so I made A save right before the landsmeet. I eventually played all the possible endings from there on the same character. Then I got the achievement. But theres a promblem. When I imported my origins character into the Witch hunt DlC the chioces I made on my first playthrough aren't the same. On my first playthrough I did the ritual with morrigan and saved fereldan and all the wardens. when I spoke to morrigan at the end of the DLC she talked about how I betrayed her by not doing the ritual. I was like WTF???



What i'm really wondering is how does the game choose what ending you took?? Ive deleted all the saves on that char but one(the one with my prefered ending). So I don't know why its giving me endings I don't even have saved. please help anyone, I'm about to start awakening and I want everything to be my way.What do you do if your Dragon Age character has multiple endings?
Whatever the last ending you did when you got the Perfectionist achievement is the one that is saved on the file you have. Only one set of choices are made in the save game ... think fourth dimensionally.
